SAMSON 3730-200010.00 regulating valve process control valve

SAMSON 3730-200010.00 is the basic model in the 3730-2 series digital electric valve positioner, mainly used for the automatic control of regulating valves in the field of industrial process control. The following is a detailed analysis of its core technical parameters, functional features and application scenarios:

I. Core technical parameters and functions

Input signal and control accuracy

Signal type: supports standard 4-20mA current signal input (two-wire system), with reverse protection function, and static damage limit is 100mA.

Control accuracy: The built-in microprocessor achieves a final control deviation of ≤1%, which is suitable for scenarios that are sensitive to fluctuations in parameters such as flow and pressure (such as small chemical reactors or water treatment systems).

No communication protocol: Unlike 3730-210010 or 3730-3, this model does not integrate HART or other communication modules, only supports basic 4-20mA signal control, and is suitable for simple systems that do not require remote monitoring.

Gas source and output pressure

Gas supply pressure: Suitable for gas sources ≤10 bar, output pressure can be adjusted to 0.2-7 bar, compatible with most pneumatic actuators (such as single-acting or double-acting cylinders).

Low gas consumption: Steady-state gas consumption <0.06 scfm, which can reduce long-term operating costs.

Stroke compatibility and installation

Stroke range: The stroke range is preset by DIP switch (such as 3.6-200mm), suitable for linear or angular stroke valves, and supports NAMUR standard brackets and VDI/VDE 3845 angular stroke brackets for installation.

Mechanical connection: Direct coupling is adopted, and the valve stem and the actuator are connected through a "V" groove and a protrusion. The structure is simple and reliable, and it is suitable for vibration environments.

Environmental adaptability

Working temperature: -20℃ to 80℃, protection level IP66, can resist dust and water splashes, and is suitable for conventional industrial environments (such as metallurgical workshops or sewage treatment plants).

No Explosion Proof Certification: Unlike the 3730-21xxxx Series, this model is not ATEX or IECEx certified and is not recommended for use in potentially explosive atmospheres.
